PIPE-COLLAR.

Specification of Letters Patent.

Application filed January 18, 1906. Serial No. 296,626.

To all whom/ it may concern:

Be it known that I, CoNsrANTIN RIEGGER,

a citizen of the United States, residing at New York, in the county ofNew York and State of New York, have invented a new and usefulPipe-Collar, of Which the following is a specification.

This invention relates to those sectional collars which are designed tobe clasped about steam, water, and gas pipes near a floor, wall, orceiling in order to conceal the openings through which the pipes passand provide a trimming for the pipes on the surfaces from which theyemerge.

The object of the invention is to provide a very simple and inexpensiveseparable pipecollar that is small and thin and that has concealedfastening means so constructed that the sections can be quickly puttogether about a pipe in comparatively inaccessible positions, such asclose to a wall, in a corner, or near a projection, and Which willfirmly and securely hold the sections together, so that the collar willsurely remain in position on the pipe and yet can, if desired, be easilyseparated without the use of any tool for removing the collar.

Figure 1 of the accompanying drawings shows a face view of a collar thatembodies the invention. Fig. 2 shows a back view of the same. Fig. 3shows a section, on greatly enlarged scale, taken on the plane indicatedby the broken line 3 3 on Fig. 2, and Fig. 4 shows an enlarged plan anda side view of one of the fastening-tongues.

The collar shown is formed of two corresponding semi-annular sections 1and 2. Each section is preferably stamped to shape from sheet metal witha small back-turned flange 3 about the outer edge and a curved bead 4 onthe front face at the inner edge. Projecting inwardly and backwardlyfrom the bead of each section are a pair of spring-fin- When thesesections are fastened together, they form an annular collar having aperipheral flange on the back and a circular bead on the front about thepipe-opening, with spring-fingers, which are adapted to clasp the pipeand hold the collar from displacement thereon, projecting backwardlyinto the opening.

Low flat loops 6 formed of metal are fastened by rivets to the back faceclose to the meeting edges of one of the semi-annular sections. Tongues7 of stiff resilient metal are fastened by rivets to the back face nearthe meeting edges of the other section so as to project across themeeting edges and through the loops on the back face of the oppositesection when the parts are assembled. In the form of the inventionillustrated both tongues are attached to the same section and both loopsare attached to the other section. One tongue and one loop could beattached to one section and the other tongue and other loop could beattached to the opposite section, if desired. Each tongue has abackwardlyextending boss 8 preferably punched from the metal when thetongue is made and each beyond the boss is bent so that the tip por tion9, when the parts are separated, extends substantially parallel with,but back from, the plane of the portion which is riveted to thecollar-section. The tip of each tongue is preferably tapered, so that itmay be easily thrust into its loop on the opposite section.

In putting this collar to use the sections are brought together onopposite sides of the pipe and tongues forced through the loops. Whenthe tongues are through the loops, the tips press firmly against theback face of the loop-section of the collar and force the bent sectionsof the tongues against the inner edges of the loops, while the bossesbear against the inner faces of the loops and hold the front faces ofthe tongues against the back face of the two sections adjacent to thejoint between them. The tongues are substantially as wide as theopenings through the loops, which are attached close to the meetingedges of the sections, and the thickness of the bosses is preferablysuch as to fillthe loops depthwise,

so that when together the parts are held rigidly at the joint againstany strains tending to fold or bend one part out of the plane of theother. The bent sections of the tongues spring out strongly and byengagement with the inner edges of the loops hold the sections togetheragainst lateral separation until sufficient force it exerted in a directline with the plane of the collar to cause the short bent sections ofthe tongue to yield. As stated, the loops are flat and extend close tothe meeting edges and the tongues are wide and flat and form a rigidbolt-like connection at the meeting edges to prevent the partsfrom'bending or folding on each other, and the resilience of the tonguesbetween the tips and the bent portions is sufficiently strong to preventthe separation of the parts unless subjected to considerable pull. Thesections of the tongues utilized for causing the frictional hold whichprevents the lateral separation of the parts are entirely beyond thebosses inside of the loops and awayfrom the j oint-that is, theresilient sections of the tongues do not extend across the joint back tothe point of fastening when the parts are together.

This collar is very simple to manufacture. It is flat and ornamental, itis easily put together, and can be quickly separated for removal, andyet the fastening is very secure, allowing stiff clasping-fingers to beused, so that the collar will not become displaced from its position onthe pipe.

The invention claimed is 1..A pipe-collarformed of two separablesections, with low flat loops attached to the back face adjacent to thejoint between the sections, and fiat resilient tongues attached to theback face and extending across the joint and through the loops, saidtongues being substantially the same width as the loops and havingbackwardly-extending bosses,

substantially the same depth as the loops and having bent resilientportions beyond the bosses which engage the back edges of the loops andthe back face of the collar, sub stantially as specified.

2. A pipe-collar formed of two separable sections having aninwardly-extending flange on its peripheral edge and anoutwardly-extending bead and inwardly-projecting springfingers on itsinner edge, with low fiat loops attached to the back face adjacent tothe joint between the sections, and flat resilient tongues attached tothe back face and ex tending across the joint and through the loops,said tongues being substantially the same width as the loops and havingback- Wardly-extending bosses substantially the same depth as the loopsand having bent resilient portions beyond the bosses which engage theback edges of the loops and the back face of the collar, substantiallyas specified.

3. A pipe-collar formed of two separable sections with low fiat loopsattached to the back face adjacent to the joint between the sectionsandflat solid tongues attached to the back face and extending across thejoint and through the loops, said tongues being substantially the samewidth as the loops and being rigid where they cross the joint and enterthe loops and having bent resilient portions beyond, which engage theback edges of the loops and the back face of the collar, substantiallyas specified.
